7mm elk bullet

I have been doing some searches for good performing 7mm mag elk bullets. From what I have gathered there are several, but I am putting the list down to 6 different types of bullets that would be good on elk. Please pick the best and why. Point out any that you believe are not good at all and why. Thanks.
